CAUTION: The installer clobbers %PATH%. There's a path1.log file stored along side the uninstaller which you can use to rescue your %PATH% Environment Variable, but it will be deleted if you uninstall (in that case, your only recourse is to do a System Restore).
*Warning* This suite can mess up your PATH variables in Windows 7, which means many of the CMD shell commands you need to use like find.exe and sort.exe will be used from the WINAVR bin folder, breaking loads of stuff. Otherwise its a good toolkit.
It had ruined my PATH variable, many programs stopped working. :( As I have already uninstalled the program, the PATH stored in path1.log was renamed to path2.log, updated with current (wrong) path and deleted. I have found some PATH in this registry: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment
This software is nice... Assuming you can get it to work for you. I read some of the reviews and I didn't want to take the risk of winavr overwriting my path directory, so I unchecked that option for the install. However, I couldn't use things like avrdude without changing the directory and running the executable. But, there is a work around that I want to share that could save someone a lot of time if they don't want to take a risk like me. Create a file called "winavr.bat" in "C:\WinAVR-20100110" with the following contents: set PATH=%PATH%;C:\WinAVR-20100110\bin;C:\WinAVR-20100110\utils\bin cmd If you want to use WinAVR, just simply double click on the .bat file and you'll be able to use avrdude, make, etc. I do not take credit for this. I would have just given the link, but I would never expect someone to click on a link in a review. Go to section 2.1.4 of this page: www.newae.com/sidechannel/cwdocs/installing.htmlokpoijoiu
